Frequently Asked Questions

About blue

1 How does blue work ?

blue and its sensor are continuously measuring the key parameters of your swimming pool. These data are automatically sent by blue and analysed by Riiot Labs’ algorithms. The results of the analysis are then communicated to you via the blue smartphone app or through notifications to people who take care of your pool.

2 What does blue measure?

blue measures the temperature (°C,°F), pH, ORP/Redox (active chlorine measurement), as well as the conductivity (total dissolved solids TDS & salinity measurement). The blue app clearly indicates your water quality. In addition to these measurements, blue algorithms collect local weather forecast information to better advise you.

3 Does blue work in automated pools (pH regulator, salt electrolysis, chlorine injections, ...)?

Yes. blue allows you to check that there is no malfunction (chlorine overdose, unstable pH, ...) of your automated water management system and notifies you if any occur. Do no forget that your water quality may vary from one location to another according to your configuration.

Probes should be calibrated one to two times per season. The blue by Riiot application warns you when a calibration is required and allows you to perform the calibration via Bluetooth. The process is very easy and only takes a few minutes.

No. blue measures and controls the parameters of your swimming pools to keep them clean and ready for a swim. If you have an automated system, it warns you of potential anomalies. If you inject your products manually, blue guides you via its application to help you use the right product in the right dose at the right time to minimize unnecessary product use.

3 Can I leave blue and the sensor out of the water?

To ensure a maximum longevity, the blue sensor must remain in a humid environment. If you have to take blue out of the water for a few hours, it is highly advisable to place it in its storage cap.
